STOVE-DOOR FRAME AND HINGE THEREFOR.

Application filed December 21, 1921. Serial No. 523,890.

To all whom it may concern:

Be it known that we, FREDERIC G. N co- LAUS and JOSEPH ROY, citizens of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Stove-Door Frames and Hinges Therefor, of which the following is a specification, reference being had therein to the accompanying drawing.

Our invention relates to improvements in stove door frames and hinges therefor.

The object of our invention is to provide a stove door frame made of angle iron which is very rigid and unbreakable and at the same time produce a frame in which all of the horizontal and vertical joints are flush, thus producing a more simple. cheap and practical stove door frame.

Another object of our invention is to produce a stove door frame which is readily assembled and which has certain details of structure and combination of parts hereinafter more fully set forth.

A further object of our invention is to provide a novel hinge construction for our improved door frame which is simple and cheap of application and construction and effective in operation. a

A still further object of our invention is to provide a novel stove door frame and hinge construction of certain details of struc ture and combination of parts hereinafter more fully set forth.

235 Other further objects and novel features of our improved construction will appear in the following specification and accompanying drawings.

In the drawings Figure 1 is a perspective view of a portion of a stove frame in which is carried our improved door frame structure; two doors are shown in the door frame, one being closed and the other in an open position.

Fig. 2 is a horizontal sectional view taken on the'line 22 of Fig. 1, looking in the direction indicated by arrow, the lower door not being shown.

Fig. 3 is a rear view of the construction 50 shown in Fig.1, both of the stove doors being closed.

Fig. 4 is a fragmental vertical sectional view taken'on the line 44 of Fig. 3, looking in the direction indicated by arrow.

Fig. 5 is a vertical sectional view taken on the line 5-5 of Fig. 3, looking in the direction indicated by arrow.

Fig. 6 is a detail perspective view of one of the lower corners of our improved door frame.

Fig. 7 is ,a detail perspective view of two of the component parts of our hinge con struction.

Referring now to the drawings in which like parts are designated by similar referonce numerals throughout the description, 1 represents an L-shaped angle bar which forms the base of the stove frame, the stove frame being made in any desired shape, rectangular, square, or the like.

Mounted upon the vertical leg a of the stove frame. base 1, there is a oven front frame 2, which comprises an L-shaped angle bar bent in a U-shape to form two uprights b and a top 0. The lower ends of the front legs of the uprights I) carry dove-tail portions 3, which fit the dove-tail notches 4 in the vertical lega of the stove frame .base 1, and are secured therein by a suitable bolt 5, carrying on its inner end a cross-arm 6 and a nut 5'. The oven frame 2 has triangular shaped portions cutfrom its front at a point 7, so that the oven frame can be bent at the apex of the notched portions and so bring their edges together to form a right angle, as clearly appears in Fig. 1 of the drawings. v

As the stove and oven frame form no particular part of our invention the description of these parts of the stove will not be gone into in any greater detail. The oven frame 2 carries by means of suitable bolts or screws 8, the oven walls 9, and positioned I about midway of the legs I) of the oven frame is an angle iron cross-bar 10 of an L-shape and it is carried or fastened in the legs b of the oven frame 2 by means of dove-tail portions 11 and bolts 12 in a similar manner to the way the legs I) of the frame 2 are fastened to the stove base angle bar 1. I

Pivotally mounted upon the cross harm is an oven door A and pivotaliy mounted upon the frame 1 is an oven door B. The

particular construction and mounting of these doors will be hereinafter described.

Referring now to the upper. oven door A,

the frame of this door is composed of a Y joints.

i .clearly appear in the drawings the uprights 13 of the door frame of the door A have a downwardly extending portion 17 which extends below the door frame and the horizontal leg 18 of the L-shaped crossbar 16 has a downwardly extending portion 19 by a front 21of any suitable material, pref I extendin 0 bent atright angles to this cross bar and of an equal length to the portions 17 of the upri hts 13. These downwardly extending portions 17 and 19 carry-a hinge pintle 20,

in any suitable manner such as shown.

The door frame of the door A is closed erably being coated with enamel to add to the appearance of the stove. The front 21 of the stove has inwardly bent edges 22 which are equal in width to the inwardly legs 23 of. the uprights 13 and top 14 o the oven door frame. The oven door A is further provided with a back 24 having inwardly extending edges 25 which are equal in width to the inwardly extending legs 23 of the door frame. As clearly appears in the drawings the lower inwardly bent edge 22 of the stove front 21 rests upon the cross bar-16 of the door frame and that the inwardly bent edges of the front lie against the inwardly extending legs 23 of the door frame. The inwardly bent edges 25' of the back 24 of the oven doorlikewise lie against the inwardly extending legs of the oven door frame but at the opposlte side thereof to the inwardly bent edges of the door front. At intervals around the door frame bolts 26 provided with nuts 27 penetrate the inwardly bent portions or edges of both the front and back of theoven door and the inwardly extend- .ing legs 23 of the door frame tofasten the front andback of-the oven door securely to the frame. 'The door back 24 is provided "with openin s 28 to allow access to the nuts 27 oflthe b0 ts 26.

, The oven door frame carries at its top a ,handle 29 adapted to engage a catch 30 car- 'ried by the top of the oven frame 2. As this handle and catch construction forms no part of this invention, a description in detail of these parts will not be given. It will be readily understood that any suitable door handle and catch can be used without departing from the spirit of our invention.

The cross bar 10 of the oven frame, bc-- fore referred to, has an inwardly extending cut out portion 32 adjacent their ends. Extending downwardly through the openings 32 of the rearwardly extending horizontal leg 31 of the cross bar 10 are the extending hinge portions 17 and'19 of the door frame which carry the hinge pintles 20. Carried by the inner side of the cross bar 10 by means of a bolt 33 and nut 34 or their equivalents are bearings 35. These bearings have central cut-out portions 36 which are adapted 'to receive the downwardly extending hin portions 17 and 19 of the door frame. At each side of the cut-out portions 36 of the bearings 35 are two outwardly, bent portions 37 adjacent to which are the vertical ends 38 of the bearings. As'clearly appears in the drawings these bearings are bolted into place beneath the openings 32 in'the cross bar 10 of the oven frame. In this position the outwardly bent portions 37 ofthe bearings receive and rotatably support the pintles 20 of the oven door hinge portions while the vertical ends 38 of the bearings 35 prevent the endwise movement of the hinge pintles in the bearing supports 37. It will be clearly the horizontal and vertical joints are flush and furthermore have provided an oven door which is hinged in a novel manner. It will likewise be readily understoodthat the hinge pintlescan be cheaply and easily replaced should this become necessary because of wear. It will also be readily seen that we have provided a hinged door in which there is used a minimum number of parts or mountings. 4

Coming now to the lower door B of the oven, this door consists of a. door frame, front and back, which are constructed in a similar manner to the heretofore described door .A. The difference of construction in the lower door- B of the oven over that of the door A is in the manner of hinging the same in the stove oven frame.

In hinging the lower door we use an additional L-shaped bar 40 which has an inwardly extending leg 41 at. right anglesto that the inwardly extending horizontal leg 41 of the bar 40 takes the place of the leg 31 of the cross bar 10 in the oven door hinging construction. The leg 41 of the bar 40 is provided with openings 44 through away with entirely.

ing below the bottom of the frame, for

which extend the portions 17 and 19 of the door frame and these portions of the door frame carry a hinge pintle 45. The hinge pintles are rotatably supported in the bearings 46 which are struck out from the bar 40 as clearly appears in Figs. 3 and 5 of the drawings. The construction of the bearings 46 of the lower door B is similar in construction to the bearings 35 of the up r door A with the exception that the bearings in the lower door form an integral part of the cross bar 40, being struck out from it, while the bearings used in-the upper door A are attachments which are bolted to the cross bar 10. The openings 44 in the stove base 1 allow the opening of the oven door B and form a stop to limit the movement of its opening, as is likewise the case in the door A construction.

It will be readily understood that specific changes in construction from the broad disclosure of our invention could be made. For instance the hinge pintles 20 and 45 could be carried in only one of the extended gortions 17 or 19 of the stove door frame.

hould the extended portion 17 of the frame be used to carry the pintle the bottom angle bar 16 of the door frame could bereversed. That is, the inwardly extending horizontal leg 18 could extend inwardly at the top instead of from the bottom as it does in the drawings. Should the pintles be supported in the extended portion 19 of the angle bar 16 the extended portion 17 could be done We wish it to be understood that the changes or modifications above referred to can be made without departing from the broad spirit of our invention and without materially changing the invention.
